Intersect boolean in animation doesn't render properly and gives blackout/whiteout
In a recent version an &quot;Exact&quot; mode has been added to the boolean modifier. It is enabled by default, and it is supposed to handle non-manifold and co-planar meshes better than the regular &quot;Fast&quot;, mode, but it is also computationally very heavy and there are still edge cases where it fails.
You can try to toggle between &quot;Exact&quot; and &quot;Fast&quot; and see if it changes anything.
Also, booleans do not work well with non-manifold meshes (eg a plane) You can try adding a solidify modifier with a very low value.
